Hello,
one thing I often thougt:
I dont know how to explain, but I often thougt that it would attract more readers to DC if they would give each (classic) (major) character a "modern" counterpart who is younger, wears a "modern" costume, has different attitude etc. but is not much considerable weaker (or maybe even stronger).
NOT!!! replacing them, but acting like a modern counterpart (NOT!! Sidekicks, but be confident and independent...)
I mean the "classic" Versions are still successfull and many people love them etc.
I think it would attract especially the ageclass of readers from 20-30....
I think especially for Superman/Clark it would be nice to also have Conner as his "modern" counterpart, who is more like the Earth-One Superman, NEW52 Superman...also has a more "modern" outfit like jeans,shirt and leather-jacket instead of the Cape etc.
So like:
Batman-Nightwing
Green Arrow-Arsenal
Diana-Donna (Cassie)
Barry Allen-Wally West
Clark-Conner
Aquaman-Tempest
Justice League-Titans (both Dick and Tims Generations)
I for example liked Wally and Barry both as Flash in Rebirth and Wallys new "modern" costume
